....I had quit nearly two years ago, when I was first diagnosed w/CHF & COPD,along w/an existing heart condition (Arithmia)...it was either quit or die....second hand smoke had never bothered me(wifey & daughter smoke)up until about a month ago when I woke up one morning & just smelled the scent of stale cig. smoke everywhere....on my clothes...on my wife's clothes...on the pillow sheets in every room of the house...after two years, I just had to have me a SMOKE...! OH the F'n horror...I thought I had it licked...I'm on the patch now (day 5)& seem to be O.K. However now I've become a complete tyrant & have banned all smoking in the house...I had no choice, my lungs were shutting down...I'm on o2 & a nebulizer...all in less than one month.
